Borderline personality disorder and DBT therapy
Borderline personality disorder (also called emotionally unstable personality disorder, F60.3) is a frequently misunderstood diagnosis. According to Finnish Käypä hoito, population prevalence is around 0.7%, but in primary care patients up to 6%, in psychiatric outpatients around 25%, and in inpatients 20% (Käypä hoito). It is therefore a major condition in the Finnish healthcare system.
This article unpacks what borderline personality means, why the diagnosis often meets resistance, and why dialectical behaviour therapy (DBT) has proven the most effective treatment.
What borderline personality means
The core is difficulty regulating emotions. Feelings ignite quickly, are intense, and last a long time. This affects everything: relationships, self-image, behaviour, decision-making. Käypä hoito names key features:
Unstable self-image, swinging between extremes. Intense and unstable relationships where another person is one moment idealised, the next devalued. Fear of abandonment, activated by small signals. Impulsivity: in eating, substances, spending, sexual behaviour, risk-taking. Self-harming behaviour and thoughts; over half show some self-harm at some point. Chronic emptiness and intense anger that's hard to control.
Diagnostic criteria require at least five features simultaneously, and they must be persistent and visible in many areas of life.
Why the diagnosis feels heavy
Borderline personality is a loaded diagnosis. The term "personality disorder" can feel like the entire person is faulty. Research says the opposite: it is treatable, and symptoms often soften with age. Käypä hoito notes "time evens it out": about 50% achieve remission in 10-year follow-up.
The diagnosis is more common in women, but this may reflect diagnostic patterns rather than true prevalence. The same features in men may be interpreted as antisocial or substance-use related.
DBT: the primary evidence-based treatment
Dialectical behaviour therapy (DBT), developed by Marsha Linehan, has proven the most effective treatment. DBT combines cognitive behavioural therapy, mindfulness, and dialectical thinking (holding two opposite truths simultaneously).
A DBT programme typically includes four components: weekly individual therapy, weekly skills groups (mindfulness, emotion regulation, interpersonal effectiveness, distress tolerance), phone consultation in crisis, and the therapist team's own consultation. Total duration is typically about a year.
DBT is available in Finland especially in specialised psychiatric care and in some private psychiatric centres. Some wellbeing services counties have built specific care pathways (Central Finland wellbeing services county).
Other treatments
Beyond DBT, mentalisation-based therapy (MBT) and transference-focused psychotherapy (TFP) have proven effective. There is no medication specifically for borderline personality, but co-occurring mood, anxiety, or sleep disorders can be treated pharmacologically.
Kela and rehabilitative psychotherapy
Kela's rehabilitative psychotherapy is available to people aged 16 to 67 whose ability to work or study is threatened by a mental health disorder. You must have been in appropriate care for at least 3 months, and a psychiatrist must have written you a B statement (B-lausunto). Kela covers up to 80 sessions per year and up to 200 sessions over three years. The reimbursement for individual therapy is 57.60 euros per session, and you pay the rest yourself. The therapist must be a Kela-approved provider, so check the therapist's eligibility in advance. Current conditions and reimbursement amounts are at kela.fi.
The treatment pathway in Finland
Diagnosis is usually made in specialised psychiatric care. The path starts with your own doctor writing a referral to a psychiatric outpatient clinic. In acute crises, emergency services are the right place.
Access to DBT programmes varies by region. Some central hospitals have their own DBT teams; in some areas care is purchased from private providers. Private DBT can be accessed without a referral but is more expensive.
What loved ones can do
The role of loved ones is hard but important. Käypä hoito recommends targeted education and peer support. A few key things:
Stay calm when the other person's emotions surge. Your steadiness is an anchor. Don't take idealisation-devaluation swings personally: it's part of the disorder, not you. Keep your own boundaries clear and consistent. This provides safety for both. Seek support for yourself too: the burden on loved ones is real.
Where to get help
Help is available via:
Your own doctor or occupational health doctor assesses the situation and refers if needed. In a crisis, the MIELI crisis line (09 2525 0111, 24/7) and emergency services are always available. Mielenterveystalo (mielenterveystalo.fi) offers information and screening tools. Kela's provider registry lists rehabilitative psychotherapy providers. The Finnish Psychological Association directory lists psychologists, some specialised in DBT.
